On condition that the numbers of participators are uncertain,this paper,based on introducing a proportion coefficientα,constructs a decision-making model of two targets,which improves the single decision- making model based on expected profits in Friedman model and Hassman-Rivett model.
在随机投标人数的条件下,通过引入基于投标商个体差异的比例系数a,建立了基于赢标概率和期望利润为决策目标的两目标投标决策模型,改进了Friedman模型、Hassman-Rivett模型的以期望利润最大化为目标的单目标投标决策模型,有效地解决了这两个模型中赢标概率和期望利润取值反方向变化而导致的决策困难的弊端。

补充资料:电能不足期望值
表示电力系统由于机组受迫停运而造成的对用户少供电能的期望值,这一指标能说明故障的严重程度,因为电力系统受限制的因素不仅仅是缺电力,更重要的是发电量的短缺。
计算EENS指标时,一般必须先制订发电机组的停运容量概率表和小时负荷曲线。对某一已知停运容量状态,则每小时不足电量等于不足电力乘以此状态的概率,即EENS=(X-R)×P(X)式中X为停运容量,R为系统备用容量,P(X)为停运容量为X的确切概率。
一年中EENS值可由下式计算:式中P(X)为第i时间段第j天第 k小时停运容量大于等于X的概率,Ci为第i时间段的系统装机容量,L为第i时间段第j天第K小时的负荷,m为一年中时间段,ni为第i时间段中的天数,K为一天中的第K小时。
电能不足期望值综合表达了停电次数、平均持续时间和平均停电功率。
